Additional information

Historical Context: Issued by the Dominican Republic between 1978 and 1981, this 1 Peso coin spans a significant transitional period in the nation's history. It marks the end of Joaquín Balaguer's "Twelve Years" presidency and the advent of Antonio Guzmán Fernández's democratic administration, a pivotal shift towards greater political openness. During this era, the peso remained the national currency amidst global economic fluctuations, and the issuance of such a substantial base metal coin likely aimed to reinforce national identity and perceived economic stability.

Artistry: The coin’s impressive 38.1mm diameter allows for a prominent display of design, characteristic of modern nationalist numismatic artistry. While the specific engraver remains undocumented for many circulating issues of this period, the obverse typically features the national coat of arms, symbolizing sovereignty and national pride. The reverse often depicts a revered historical figure or an allegorical representation of liberty, rendered in a robust, classical-modern style, emphasizing national heroes and foundational principles.

Technical/Grading: Struck in copper-nickel, weighing 26.7 grams, this large planchet coin is prone to varied strike quality. Key high-points for wear or strike weakness typically include the highest relief elements of the coat of arms, such as the shield’s crest or the surrounding banners, and for portraits, areas like the hair or cheekbones. Its substantial size makes it susceptible to bag marks and contact abrasions, particularly on the fields. Well-preserved examples should exhibit a strong cartwheel luster across both surfaces.
